Complications in reverse shoulder arthroplasty

Reverse Total Shoulder Arthroplasty: A Review The reverse total shoulder arthroplasty prosthesis can nature of the reverse total shoulder arthroplasty.

Analysis of a retrieved delta III total shoulder prosthesis.

examined glenoid component stability with regard to the angle of implantation

The purpose of their study was to evaluate forces and micromotion in glenoid components attached to polyurethane blocks at 15°, 0°, and 15° of superior and inferior tilt

They suggested that implantation with an inferior tilt will reduce the incidence of mechanical failure of the glenoid component in a reverse shoulder prosthesis [17].

The DePuy Delta III reverse prosthesis, ..

It is different from the native anatomy of the shoulder and the conventional total .The Reverse Shoulder Replacement is a newly approved implant that has been is unable to raise her arm because the humeral prosthesis is dislocated .The reverse total shoulder Candidates for a reverse total shoulder arthroplasty is Reverse Total Shoulder Arthroplasty Components.

Reverse total shoulder replacement is a ..

Conclusions: In the presence of severe loss of active elevation and external rotation, combined latissimus dorsi transfer and reverse total shoulder arthroplasty can restore elevation and external rotation, at least in the short term.

DELTA XTEND™ Reverse Shoulder System - DePuy …

Therefore, 3 DOF was createdThe problem is that this reconstruction again provides 3 DOF less that anatomic mimic of shoulderFinite element analysis of the reversed shoulder prosthesis is going to be don in order to find the amount of the micro motion at gelenohumeral joint In order to find the micromotion; deformation, mesh displacement and failure of the parts at contact region is going to be assessedAccording to the result a new part is going to be designed in order to solve the problem of RSP and elevate the degree of freedomThe stresses will be distributedThe pain will be reliefed considerably

Figure.4Thanks for your attentionConclusionThere are some dieases deal with reverese shoulder anatomyThese diseases reduce shoulder function performancesHowever, there are some complications that do not let RSP to act like human shoulder mimic anatomyTheses complications can be improved by changing some factors, i.e COR, gelenoid head diameter, humerus neck shaft angle and etc.Software simulation is novel approach to be used for DOF elevationOutcomes the simulation endeavor are useful for new design procedure [1] Bigliani LU, Craig EV, Butters KP.

reverse total shoulder portfolio offers optimal ..

However, by compensating with extra elevation, horizontal flexion and elbow, the patients were able to complete most of the ADL [15]

Reverse shoulder prosthesis parts has been provided and used for simulation The parts have assembled in Ansys software in order to do the rigid body dynamics simulationFor each part, a specific material property was allocated Between each two parts a specific joint was definedAt gelonohumeral joint between gelenoid head and gelenoid cup a spherical joint was defied.
